The cost of 18% solar cells has gone down 100 to 1 in my lifetime to $0.35/W. The cost of 36% cells (space industry) has gone up to $350/W. So the cost to double the power on a car roof multiplies the cost by x1000.
One can get factory seconds of the $350 cells for $50, but "seconds" from the space industry can NEVER meet the xMILLION demand for car production.

That "obvious question" has a pretty obvious answer, but the piece's writer, Michael Strong, appears to be both too ignorant to know it, and too lazy to look it up. > The Japanese automaker is tinkering with ultra-thin solar panels used > for satellites to produce a solar-powered Prius.

Guess what: that's part of the reason that PV on the vehicle isn't very practical. > The electricity from the panels travels directly to the drive battery, > allowing the Prius to charge while driving or parked. > > Even though the panels are super thin, the truck of the Prius is > weighted down with an extra 180 pounds of batteries that are charged by the solar panels. Now, which is it? Does the PV system charge the traction battery, or does it charge some extra 180lb battery? Also, the WHAT of the Prius?
